Expert writing Tips

Best practice

Always use "does she know how" instead of "does she knows how". The auxiliary verb 'does' requires the base form of the main verb.

Common error

Avoid using the third-person singular form ('knows') after the auxiliary verb 'does'. The correct form is always the base form of the verb ('know').
